With both X – The Movie and the X television series, X is one of those older animes that talk about post apocalytical battle.
Basically, the main character must choose a side to fight it out and depending on his choice will undoubtedly change the course of the world. Pretty usual, and the fights are actually pretty good if you watch the anime first. In fact, I would recommend not to watch the movie until you finish watching the anime itself since it wouldn’t make as much sense otherwise.
The film itself is the exact same story but with a bit more focus on Kamui and less on the Dragons of Heaven and Dragons of Earth.
All in all, it was a pretty good series, although I have to say that the very first episode was entirely strange until you realize later on what it meant. Basically, it’s supposed to be a primer for the series for those that haven’t read the manga, but it really just gives away bits and pieces of the story. The only bad thing about it is that you don’t know how each part fits in since that’s all the dreamgazer for the Dragon of the Earth saw. For the most part, the entire storyline is pretty tragic and sad, but that’s also to be expected from such apocalyptic fiction.
Personally, I still find that my favorite of this genre still is Ergo Proxy, but X definitely had a nice feel to it nonetheless.
